A wave of tourists have gone missing or been found dead after the Michael Mosley tragedy in Greece’s 40C heatwave.

The body of an American tourist has reportedly been found on the Greek island of Mathraki. They are one of at least seven missing or dead - a Dutch man was found dead on Samos, two hikers were found death on Crete, one American went missing from Amorgos and two French tourists from Sikinos.

This follows the recent death of TV doctor and presenter Michael Mosley, who was found dead on the island of Symi following days of being missing.

His body was found in a rocky area, and investigators concluded that he died of natural causes the day he went missing.

Many, if not all of the victims, were on hikes when they disappeared.

The American found dead on Mathraki was a 55-year-old man who was seen alive in a bar last week. He was found on a deserted beach.

Greece’s temperature is partially responsible for the spike in missing and dead tourists. In Greece, heatwaves are temperatures which exceed 38C for at least three days.

The country is suffering its earliest heatwave on record, with winds from North Africa pushing up the temperature.

Schools and top tourist attractions such as the Acropolis have been forced to close to allow people to escape the heat.

On Saturday, officials reported the death of a 74-year-old Dutch tourist who went missing after going for a solo hike on another island, Samos.

Meanwhile, a search continues for 59-year-old Albert Calibet, a retired police officer from California. He is reported to have disappeared on Amorgos last week after similarly failing to return from a hike.

Greek officials are searching the island of Sikinos for two French women, aged 73 and 64, too, according to French news agency AFP.
